- Leners Patent 1vol 87,944, ma M11/rch 16,1869.

To all 'whom 'it may concern-:

'invented a new and useful Improvement. in Flood- Gates; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon.v

Figure l represents a sidey elevation of my watergate, with two of the posts broken away at the groundline.

Figure 2 represents an edge view of the same, with a portion of the frame and posts broken away to exhibit the fastening. v

In the accompanying drawings- A B O denote three posts, .which have mud-sills, I), secured by mortise and tenen, or spikes, to their feet, and braces, a a, may also be applied, as represented in the drawings, for the purpose of holding the posts rmly in the ground; and, for the same purpose, crosspins,b, may be inserted in the bottoms ofthe posts.

Thethree posts may be set into the ground, in the bed of the stream of water, or creek, to bringthe sill, E, down to the ground-line, represented at x x.

The plate F will be secured on the tops of the posts, in any substantial manner.

The gates, H, are constructed of square frames c c, d d, and boards e e, the latter being nailed upon one side only of the frames.

The gates H are suspended between the posts by bolts g, which pass through the posts and the framepieces cc of the gates, at a point about two-thirds of the length of the gates from their bottom thereof. The gates will freely open and close by a swinging motion, moving upon the bolts gas hinges.

The boards which cover the frames of the gates on one side, will be fitted up close to each other, to prevent flood-wood from becoming fastened therein.

A sucient space is left open, vbetween the bottom of the gates and the sill E, to admit the ordinary quantity of water to ow through it, which is supplied by the creek across which the gate is erected.

The upper surface of sill E is rounded olf, to prevent sand and earth from lodging thereon.

Through the central post B there is a'mortise, o, through which the metal bar p'is inserted, and' pivoted by a bolt, seen at t, fig. 2.

The pin k is inserted andsecured in a hole in the end of the bar p, near the post B, to serve as a stop and fastening to the gates H.

The other end of bar. p, 'which extends out at the front side of the gates H, is provided Witha wooden block, M, which serves as a oat.

N is a block, secured to post B, to prevent the gates fromA being opened in the opposite direction from that in which the water Hows.

At the bottom of the gates, the twodnner framepieces c c extend below the other parts of the gates, and atI the rear side thereof these two frame-pieces c c are rounded oil' in the arc of a circle, forthe purpose of allowing the pin k to move easily around and below them.

When the stream, or creek,'is swollen by a flood, the water will cause the float- M to be raised up, which movement will cause the bar p and pink to occupy the position represented in iig. 2 in dotted lines, which will allow the gates to be opened by the flood; and when the flood subsides, the gates will close themselves by their gravity, and the block N and pin It will secure the gates from being pushed open by animals.

A single gate, or any connected number of gates, making a continuous fence, maybe erected upon the same principle.

Having fully described my invention,

What I claim, and desire to secure by Letters Patent, is-

The swing-gate H and its fastening, consisting of the bar p, pin k, and float M, arranged to operate, in combination with each other, within the frame, conv sisting of the posts A B, plate F, and sill E; substantially as and for the purpose described.

In testimony whereof, I have hereunto set my hand, this 19th day of December, 1868.
